Table 6. Use of STA Bits for Identical I/O Data Rate Operation
* - only in the 44 pin packages.
** - for Data Memory Read operations A0 is not required since two nibbles are provided per read access.
Table 7. Use of STA Bits for Different I/O Data Rate Operation
Note: In rate conversion applications, Data Memory subsections have different sizes than Connection Memory subsections. This
implies that different address inputs are used to select individual positions within the subsections for each type of memory.
